We're celebrating my grandma's 100th birthday next month and I need ideas on table decorations for a butterfly theme party. My "thrifty" mother is using the white table cloths provided by the church so I'm thinking of running pastel ribbon down each table with maybe ivy but I need something else.

How about getting all the children attending the party to draw/colour in/otherwise decorate a butterfly cutout, or even all the adults? you could also sprinkle small paper punched butterflies in amongst the ivy.
